no power in trailer while hooked to shore power

[08ramguy]

Ok this is new and have searched this site with all that i can think of, the problem i am having is when the batterys are hooked up (2) I have no power in my trailer, to include when I'm hooked to 110v, however when I unhook the batterys from the trailer and hook up shore power every thing works fine....if every thing works in trailer, lights, heater, microwave then I think that the converter seems to work....batterys will not charge, hooked to shore power or when generator is running....on that note the gen will only start if I jump it.....like stated no power in trailer with gen running....so confused any ideas.....fuzes are all good.....its a 26fs keystone nrg....2006...sorry if this doesnt make sense but im lost...:confused:

You have two batteries? 6 volt of 12 volts? If they are 6 volt, they need to be connected is series, aka ground of the camper to the - terminal, the + terminal of that battery to the - of the next, and the + of the battery to the + of the camper.

If they are 12 volts, they need to be connected in Parallel. - to - to ground, and + to + to + of the camper.

It sounds like the batteries are not connected properly or need to be replaced. Also check for loose and/or corroded connections.

Like Shoey said, I think you have a polarity problem with your batteries (or questionable voltage) and possibly have blown the in-line fuse to the batteries. Check the voltage between the two trailer cables to see if you have 6v, 12v or 24v dc. If 6 or 24 the batteries are connected wrong. Check to see if they are wired as Shoey explained, then look for the in-line fuse.

I guess the title should be changed to “No power when batteries are hooked up.”

Don’t forget the possibility that one or both batteries are dead, so don’t forget to completely disconnect them and check each one for proper voltage.

I sure hope you have a voltmeter.

OK, so I got it figured out, I had one cable not conected to the right terminal, I had a black cable (thinking it was a neg) hooked to a neg. terminal, so I hook it to a positive terminal like it was supposed to and now I have power in the trailer.....and new battery's......thank you to all that posted a response it got my thinking, and problem solved....:bdance:

Glad you got it all figured out. I didn't catch on about the backwards wire coloring until I started reading these forums. I don't know who thought that was a good idea, or why.

A good reminder for all of us....

In the RV world, at least around the battery connections, white is usually ground (-) and black is usually hot (+).

I am "forever getting confused" in the conversion from white to black and black to red (or is it ?????) So, to solve my "hurry up it's raining" situations from becomming "rectally painful", I used heat shrink and put a 1" piece of red on the ends of every black battery cable and a 1" piece of black heatshrink on the ends of every white battery cable. Now, when in a hurry, rather than stopping to "think it through" while trying to hurry through the job, I have a visual reference that relates to "automotive electrical systems" as well as the cables that relalte to "household electrical systems" Makes for a reassuring battery connection when things are going south in a hurry because of weather or other factors.

Interesting..... in the marine world neutral is going to yellow.....
